| Abstract: | This paper analyses the factors influencing the exposed areas, and studies the rules how to get the exposed areas from one phase to the others. Based on PSCAD/EMTDC, this paper presents a distribution system. The exposed areas of voltage sags, which could provide the basic rules for strengthening the power network, selecting the optimum operation mode, and selecting the position connecting the sensitive load with the distribution system, can be estimated by utilizing the fault simulation method. |

| Keywords: | voltage sags exposed area fault simulation method sensitive load |
